Finding the maximum element in tuple list

In this article, we are given a list of tuples. We need to create a Python program to find the maximum element in the tuple list.

Input: 
[(4, 1, 6), (2, 3, 9), (12, 7, 5)]

Output:
12

We need to iterate through all the elements of the tuple list and find the maximum value from all of them which is our required value.

Method 1:

One method to find the maximum element of the tuple list is by iterating over the list of tuples using a generator expression and then finding the maximum value from the resultant collection/iterator using the max() method.

# Python program to find the 
# maximum element in tuple list
  
# Initializing and printing 
# the list of tuples 
tupList = [(4, 1, 6), (2, 3, 9), (12, 7, 5)]
print("The element of list of tuples are " + str(tupList))
  
# Finding Maximum elements 
# in Tuple list 
maxVal = max(int(j) for i in tupList for j in i)
print("The Maximum value from the list of tuples is : " + str(maxVal))

Output:

The element of list of tuples are [(4, 1, 6), (2, 3, 9), (12, 7, 5)]
The Maximum value from the list of tuples is : 12

Method 2:

Another method to solve the problem is by flattening the list of tuples using the from_iterable() method from the chain library. Then, we will find the maximum value from the created the map() using the max() method.

# Python program to find the 
# maximum element in tuple list
  
from itertools import chain   
  
# Initializing and printing 
# the list of tuples 
tupList = [(4, 1, 6), (2, 3, 9), (12, 7, 5)]
print("The element of list of tuples are " + str(tupList))
  
# Finding Maximum elements 
# in Tuple list 
maxVal = max(map(int, chain.from_iterable(tupList)))
print("The Maximum value from the list of tuples is : " + str(maxVal))

Output:

The element of list of tuples are [(4, 1, 6), (2, 3, 9), (12, 7, 5)]
The Maximum value from the list of tuples is : 12
